Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-5, the present invention provides an embodiment: a pneumatic angle seat valve comprises a valve seat 1, a connecting part 2 arranged on the valve seat 1; the connecting part 2 is connected with a cover plate 3, and an air cylinder 4 is fixed on the valve seat 1 through the cover plate 3; the cross section of the connecting part 2 and the cover plate 3 is rectangular, and the connecting part 5 penetrates through the cover plate 3 and the connecting part 2 in threaded fit, so that the air cylinder 4 is fixedly installed on the valve seat 1.

In conclusion, the cover plate 3 is fixedly connected with the connecting part 2 by the fastener 5, so that the problem that the sealing element is staggered or broken when the cover plate rotates due to the fact that the cover plate is directly in threaded connection with the connecting part in the conventional starting angle seat valve is solved; secondly, the cover plate 3 and the connecting part 2 can be fixedly connected through the fastener 5 on the outside, and the problems that the cover plate is inconvenient to screw due to the fact that the existing cover plate of the starting angle seat valve is in direct threaded fit with the connecting part, and the cylinder rod is abraded when the cover plate rotates are solved; and after the cover plate 3 is attached to the connecting part 2, the working stroke of the cylinder rod cannot be influenced, so that the normal opening and closing of the valve core cannot be influenced.

On the basis of the scheme, as the end face, away from the cylinder 4, of the cover plate 3 is further provided with the support ring 31, the support ring 31 is arranged to enable the sealing ring to be sleeved outside the support ring 31, when the cover plate 3 and the connecting part 2 are closed, the sealing of the joint of the cover plate and the connecting part is realized, and the leakage of media is reduced.

For further protection of the cylinder rod, a supporting column 30 is further arranged on one end face, facing the connecting portion 2, of the cover plate 3, the supporting column 30 is in threaded fit with the outer wall of the sleeve 9 through an inner threaded hole 32 formed in the supporting column 30, the sleeve 9 is sleeved outside the cylinder rod through the scheme, so that the cover plate 3 can only rub on the sleeve 9, damage to the cylinder rod by the cover plate 3 is thoroughly avoided, and meanwhile due to the arrangement of the inner threaded hole 32, one end of the sleeve 9 can be fixed to the cover plate 3.

Furthermore, because the lower bottom surface of the support pillar 30 is also provided with the step surface 33, when one end of the sleeve 9 is abutted against the step surface 33, the sleeve 9 is limited from moving continuously, so that the problem that the working stroke of the cylinder rod is influenced due to over tightening of the sleeve 9 can be avoided; meanwhile, the sealing ring is placed on the step surface 33 and then connected with the sleeve 9, and the sealing performance between the sleeve 9 and the step surface 33 can be further ensured.

Furthermore, because the support column 30 with still be equipped with annular 34 between the support ring 31, consequently utilize the space that annular 34 formed, the shaft coupling of being convenient for is at the inside free rotation of valve seat 1, reduces the friction between shaft coupling and the apron 3, and then promotes the stationarity of cylinder during operation.

On the basis of the scheme, because the installation part 6 is arranged on the cylinder 4, and the installation part 6 is in threaded fit with the outer wall of the sleeve 9, the other end of the sleeve 9 can be fixed on the cylinder 4, so that the working position of the cylinder 4 is fixed, and the working reliability of the cylinder 4 is improved.

Furthermore, because the sleeve 9 is further provided with the external thread part 7, and the baffle plate 8 is arranged below the external thread part 7, the connecting distance between the cylinder 4 and the sleeve 9 is limited by the baffle plate 8, so that when the baffle plate 8 is abutted against the mounting part 6, the cylinder 4 and the sleeve 9 can be fixedly connected, and further, the problem that the valve core is not completely opened and closed due to the fact that the cylinder rod enters the valve seat 1 for too long length is avoided.

Furthermore, because the quantity of fastener 5 is four, just fastener 5 is the hex bolts, consequently when realizing that apron 3 and connecting portion 2 are reliably connected hex bolts convenient to use, the instrument of screwing up the hex bolts is little, the further be convenient for cylinder 4 and valve seat 1 be connected.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
